ASTRI-Horn is back in the spotlight

After a major upgrade and calibration phase, the ASTRI-Horn prototype on Mount Etna has proven to be a highly successful instrument. In addition to the scientific results achieved, the telescope has confirmed the validity of the technologies employed, which are also used by the ASTRI Mini-Array and the SST telescopes of the Cherenkov Telescope Array Observatory (CTAO). It will soon be used as a testbed for the study of volcanoes through Cherenkov muon observations.
